[QUOTE="lancetkenyon, post: 2400182, member: 68875"] The benefits of some wildcats are not ONLY more case capacity. But case design too. Case in point, the 6.5SLR. Takes a .260 Rem, and blows out case wall taper but the body/shoulder junction stays in the same place, but pushes the neck/shoulder DOWN to form 30°, increasing neck length. So you get .260 Rem case capacity, but gains the neck/shoulder design of the 6.5x47L, a known case design for accuracy. But if you are looking at pure speed gains, a .75% charge weight increase or better wilp make a noticable difference, and so does a 30° or 40° shoulder. The shoulder steepening process also benefits case life, throat erosion, case growth limiting, etc. [/QUOTE]
